We're dividing 15190280 by 699 
The aim is to understand the frequency of 699 in 15190280.

Moving on to step 1:
1 divided by 699 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 699

Moving on to step 2:
The number 699 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 699

Going ahead to step 3:
When dividing 151 by 699, we get 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Take the next digit (9) from the dividend and append it to 151, then repeat: 1519 / 699

Advancing to step 4:
1519 divided by 699 is 2 with a remainder of 121.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1398 from 1519 leaves us with 121.
Bring next digit (0) of the dividend behind the 121 and repeat the process: 1210 / 699

Step 5:
699 goes into 1210 1 times with a remainder of 511.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 699 from 1210 to get 511.
Bring next digit (2) of the dividend behind the 511 and repeat the process: 5112 / 699

On to step 6:
699 can be fit into 5112 7 times, resulting in a remainder of 219.
The next digit of our result is 7. 
Result so far: 217.0
If we subtract 4893 from 5112, we get 219.
Include the next digit (8) from the dividend after 219, then repeat: 2198 / 699

Going ahead to step 7:
When dividing 2198 by 699, we get 3 with a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 2173.0
If we take 2097 away from 2198, we end up with 101.
Take the next digit (0) from the dividend and append it to 101, then repeat: 1010 / 699

Let's proceed to step 8:
The number 699 fits into 1010 1 times, leaving a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 21731.0
If we subtract 699 from 1010, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Going ahead to step 9:
3110 divided by 699 is 4 with a remainder of 314.
Use 4 as the next digit of our solution. 
Result so far: 21731.4
The remainder is 314 after subtracting 2796 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 10:
699 can be fit into 3140 4 times, resulting in a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 21731.44
Subtract 2796 from 3140 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 21731.44, with a leftover of 0.344.
